Troubleshooting guidance
1) M.NOT RUNNING (Motor does not run)
The protective function is
activated to bring the inverter
to trip.
Press to display the
cause of the trip.
The inverter's main circuit power
has decreased or a phase in the
power supply is lost. Check the
power supply.
Both start signals STF and
STR are ON or OFF.
MRS signal is ON.
The inverter starting
frequency (Pr. 13 ) setting is
higher than the frequency
currently set.
The current input select
signal AU remains OFF.
(not ON)
Neither of and are
pressed in the PU operation
mode.
The inverter cannot start because
the inverter starting frequency
(Pr. 13 ) is higher than the
maximum frequency (Pr. 1 ).
The inverter cannot start because you
attempted to run the motor in the
direction in which forward or reverse
rotation is inhibited as set in Pr. 78.
The inverter cannot start since the current
limit function is activated. Press to
display the estimated cause that the
current limit function was activated.
The inverter does not start because the
inverter need not start the motor as a
result of the arithmetic operation of PID
control.
The inverter will not restart since the automatic restart after
instantaneous power failure select signal CS is OFF. It is estimated
that an instantaneous power failure has occurred or the inverter in
the commercial power supply switch-over operation mode.
